Answer:
16x+16
Explanation:
The perimeter is all of the sides added up. On a rectangle, only 2 sides are needed to know the perimeter because measurements are equal on both sides.
1) Write equation
2*5 + 2(8x+3)
2) Distributive property and multiply
10 + 16x + 6
3) Combine like terms
16x+16
The x-intercepts of a function are used to express the function into factored form:
From (1/2, 0)
(x - 1/2)
From (6, 0)
(x-6)
(x - 1/2) (x-6) = 0
(2x -1)(x-6) = 0
The function is:
B. g(x) = (x – 6)(2x – 1)
Answer:
880 high-quality version
Step-by-step explanation:
I think the below is your full question:
<em>A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?</em>
Here is my answer:
Let x is the number of high-quality version
So the number of standard version= 1290 - x
We also know: total download size of 4821 MB. which means:
4.5x + 2.1(1290-x) = 4821
<=> 4.5x+2709-2.1x=4821
<=> 2.4x=2112
<=> x=880
So there were 880 high-quality version
Answer:
Step-by-step explanation: I'm not sue if the x's are squared so i didn't squared them but i got : 23x³-6x²
+13x-3
